BUFFER.

This invention relates to buflers and has for its'primary object to provide a novel and efficient spring buffer particularlydesigned for use in railway stock or freight cars, but is, of course, not necessarily limited to such use.

In the transportation of live stock, the movement of cars causes the stock to sway often striking against the side and end walls of the car and causing severe bruises to hide and flesh of the animals.

It is, therefore, the object of this invention to so arrange the improved buffers in stock or freight cars as to be engaged by the swaying live stock, during movement of the car, and thus prevent bruising or other injury to the live stock by yieldably retarding their swaying movement.

With these and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 represents a fragmental longitudinal sectional view through a stock car, illustrating the improved buffers applied to use, Fig. 2 represents a fragmental horizontal sectional view through the car on the line 22 of Fig. 1, Fig. 3 represents an enlarged detail sectional view, taken in the plane of Fig. 2, illustrating one of the cushioning elements of the buffers in detail, Fig. 4: represents a sectional view on the line i4: of Fig. 2, Fig. 5 represents a longitudinal sectional view through one of the cushioning elements of the buffers, and Fig. 6 represents a detail sectional view on the line 66 of Fig. 3.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 8 indicates the floor of a stock, freight, or other railway car of the usual construction including the vertically Specification of Letters Patent.

disposed side beams or uprights 9 to which are secured the inner and outer side walls 10 and 11 forming one side of the car.

-The buflers, designated generally by the numerals 12, are arranged along the sides of the car at a suitable height above the floor 8 to be engaged by the sides and rumps of the cattle as the latter are swayed by the movement of the car. While in the accompanying drawings the buffers are shown applied to'only the side of the car, it will be understood that the same may be arranged along both sides and the end walls of the car.

Each bufler 12 includes a plate 13, preferably of rectangular formation, and connected adjacent each'corner with a tensioning element, designated generally by the numeral 14, which normally retains the plate 13 in extended position. Each tensioning device includes a base plate 15, rigidly secured to the inner surface of the outer wall 11 of the car side and having a central aperture 16 loosely receiving the housing or cylinder 17 having an exteriorly threaded end on which is fitted a stop flange 18. The base plate 15 is formed with a plurality of transverse apertures 19 arranged in spaced relation to the centrally located aperture 16 and receiving the shanks of bolts 20, which latter are provided with nuts 21 and heads 22. The bolts 20 are loosely mounted in apertures formed in the flange 18 and the latter is normally retained in engagement with the adjacent surface of the base plate 15 by the tension of springs 21, coiled about the bolts 20 and engaged at one end with the heads 22 and at their opposite ends with the flange 18.

Plungers or slide rods 23 are slidably mounted in the housings 17 and are formed at their opposite ends with heads 27 and 25. The head 27 is received within the housing 17 and the head 25 at the exposed end of the plunger is secured adjacent one corner of the buffer plates 13. A cap 26 is removably fitted over the end of each cylindrical housing 17 and is formed with a central aperture receiving the plunger 23.

A spring 28 is arranged in each housing 17, is secured at one end between the cap 26 and the adjacent end of the housing 17 and is secured at its opposite end to the head 27 of the plunger 23, whereby inward movement of the latter with relation to the housing 17 is yieldably resisted by the spring 28 plate 13 is permitted limited vertical or lateral swinging movementagainst the tension of the springs 21', lines in Fig. 5. 7

What is claimed is:

as suggested in dotted .1. A buifer including a buflier plate, a"

base plate, a housing movable relative to said base plate, means for yieldably retarding the movement of said housing with relation to said base plate, and yieldable meansconnecting said housing with said. bufier I plate.

housing with relation to said base plate, and yieldable means connecting said housing with said bufier plate.

3. A buffer including, a buffer plate, a baseplate, a housing movable relatively to I 7 said base plate, a stop flange carried by said housing adapted to engage said base plate for limiting the tilting movement of the housing with relation to the base plate, means normally retaining said flange in engagement'with said base plate, and spring retarding means connecting said buffer plate Wlth sald housing.

41A bufier'including a buffer plate, a

taining saidflange in engagement with said base plate, .a plu'nger reci-procably mounted 1 in saidhousing and being connected with said buifer plate, and'means for retarding the inward movement of said plunger with a V relationto saidhousing. 2. A 'bufier including a bufier plate, a base plate, a housing movable relative to said base plate, means for limiting andv yieldablyretarding the movement of said.

5'. A vbuffer; including a buffer plate, a base plate,..a housing movable relative, to said base plate, means foryieldably retarding the movement of saidhousingwithrela- Z tionto saidbase plate, and means connecting said housing with said buffer plate.

In testimony whereof I aflix my signature in presence of two witnesses.
